摘要 目的观察钙离子载体A23187对人红白血病细胞株K562超微结构的影响,为白血病的治疗提供新思路。方法体外培养K562细胞,密度增至(1-2)×10^5几时随机分为观察组和对照组(容积均为5mL),观察组取2mmol/L细胞溶液加入A23187溶液7.5灿,至最终浓度为3panol/L;对照组加入等体积生理盐水。细胞培养到第10、20和30Jnin时,依次取两组细胞溶液离心、制备超薄切片,H-7500型透射电镜下观察其超微结构。结果对照组K562细胞超微结构无明显改变;观察组K562细胞线粒体呈现空泡样改变和基质深染。结论钙离子载体A23187在体外可能通过改变人红白血病细胞株K562细胞超微结构诱导其凋亡,此为白血病的临床治疗提供了一种新思路。
